  • Patent number: 11773977
    Abstract: Systems and methods include providing an annular bimetallic seal for an assembly. The bimetallic seal includes a first sealing component formed from a first material, a second sealing component formed from a second material that is different than the first material, and a joint formed between the first sealing component and the second sealing component. The bimetallic seal is configured to form a radial seal between a first assembly component and a second assembly component formed from dissimilar metallic materials. The coefficient of thermal expansion (CTE) of the first material and the second material are configured maintain the radial seal at extreme operating temperatures between the dissimilar metallic materials of the components of the assembly.

  • Patent number: 11002391
    Abstract: The present invention is directed to a high-pressure bi-directional sealing system having circumferentially extending outer support rings (1520, 1900), annular, axial seals (1600, 1800) between the outer support rings (1520, 1900) and a circumferentially extending inner support ring (1700) located between the annular, axial seals (1600, 1800). The outer support rings (1520, 1900), seals (1600, 1800), and circumferentially extending inner support ring (1700) are located within a space between an outer tube (1502) and an inner tube (1504) that is telescopically disposed within the outer tube (1502). Seals (1600) and (1800) are oriented in opposite directions. Specifically, the opening of seal (1600) is facing in a first direction and the opening of seal (1800) is facing in a second direction that is opposite the first direction. This configuration enables the high-pressure bi-directional sealing system to handle pressure in both directions.

  • Patent number: 9551420
    Abstract: A sealing ring (10) includes in a diametrical cross-section a body section (12), angularly spaced sealing legs (16) and (18) that extend from the body section (12) and angularly spaced sealing legs (22) and (24) that also extend from the body section (12). Each sealing leg (16, 18, 22, 24) extends to a beveled end (28, 30, 32, 34), respectively. Beveled ends (28, 30, 32, 34) form a seal with a surface when sealing ring (10) is subjected to compressive forces. Sealing legs (16) and (24) are coplanar. Sealing legs (18) and (22) are coplanar. A first centering leg (40) extends from the body section (12) and is between sealing legs (16) and (22). A second centering leg (44) extends from the body section (12) and is between sealing legs (18) and (24). The first and second centering legs (40) and (44) are coplanar.
